Diamond's brother 'asked to be fall guy'

Olympic shooter Michael Diamond's brother says he was pressured to be the "fall guy" as the gold medallist fought drink-driving and firearm charges while bidding for selection for the Rio Games, a court has been told.

Following a dispute over loud music at a party at his Nelson Bay home, which ended with his 44-year-old brother's arrest, John Diamond says he was asked to "make out to be the bad person" during a meeting with his mother and the Olympian's former solicitor.

"He wanted me to be the fall guy," Mr Diamond said at a hearing in Raymond Terrace Local Court, north of Newcastle, on Tuesday.

Their mother mentioned at the meeting that she was concerned Michael would not be selected for the Rio Olympics in August.

Diamond remains stripped of his gun licence after missing out on what would have been his seventh Olympic Games.

During the meeting, the trio also discussed John Diamond's affidavit, but when shown the document in court, Mr Diamond said the signature on it was not his.
